P4 turned into scientists for the afternoon.  We sorted materials into liquids, solids and gasses and recorded our ideas in our jotters.  Next we investigated which solids would dissolve in water.  We had to keep some variables the same so that our test was fair.  We only changed one variable: the type of solid we put in the water.  The results were very interesting.

Why don’t you try some dissolving experiments at home and record your findings?
